But it isn't fair rule.
Look at situation as below.
#1 in some country has the best squad (he bought them earlier). #2 meet him in last 32 round and #3 meet him in last 16 round. #1 can buy new players before this match and #2 can't. It isn't fair.

I'm sure You prefer win cup than gain 250k ;-) So profits aren't essence of this problem ;-)
